TOOL.

Application filed February 20, 192:5. Serial No. 10,530.r

ates to improvements in It is one of the objects of the present invention to provide an attachment for a depth gage which will convert the same into a combination tool.

A further object provide a unitary of the invention is to attachment for depth gages so designed that it can be readily attached to a depth g age, by means of which attachment and a slight modification of the gage, the gage may tools, including an inside caliper,

a micrometer, a scale and a gage.

caliper,

A further object be used as a number of an outside the invention is to provide an attachment of the class described which can be fitted t o a depth gage very easily, the slight modifications required in the gage being readily accomplished by the ordinary mechanic,

A further object of the invention is to provide an attachment of the class described which can be sold as a unit, which is of very simple construction,

facture, is strong and durable,

is inexpensive to manuand is well adapted for the purposes described..

vWith the above and other obj ects in view, the invention consists of the improved tool,

and its parts and in the claims, and

combinations as set forth all equivalents thereof.

1n the accompanying drawing in which the same reference char acters indicate the same parts in all of the views :V

Fig. 1 is a view of a de th OauO'e of ordinary construction;

Fig. 2 is a view of an ordinary depth gage fitted with the improved attachment, the

depth gage being slightly7 modified to adapt it to the attachment; y

Fig. 3 is an edge view of adepth gage fitted with the attachment;

Fig. il is a longitudinal sectional view thereof; and

Fig. 5 the adjustable gage.

Referring now drawing, a depth gage of ing a graduated in the slot 9 of adjustably clamped a shouldered stud 11 ing 12 in the cross arm.

is slotted as at 13 to receive d the upper end portion tion of the stud the slidable scale an it will be seen ordinary construction havscale or rule 8 slidable witha cross arin10. The scale is f is a sectional view taken through cross member of the depth more particularly to the that Fig. 1 illustrates in position by means of passed through an open- The lower end porof the stud is reduced and threaded to rei ceive a turn cap 14.

A coiled spring 15 surrounds a portion of the stud 11 and is confined within an opening in the cap 14 and bears against a washer 16. By this construction the stud is under tension at all times and the scale is held in adjusted` position even when the cap 14 is loosened.

rIhe invention resides particularly in an attachment for converting the depth gage illustrated in Fig. 1 into a combination tool and said attachment comprises a tapered arm 17 havinga slotted or bifurcated inner end receive one end portion of the portion to scale 8, the

means of a screw 17 being clamped thereto by 19. The inner edge portion of the arm is beveled as at 2O and the outer taper-ed end portion is reduced and bevn 1, for the purpose hereinafter to be set forth.

After attaching the arm 17 to the end portion of the scale, the depth gage may be easeled as at 2 ily vid-ed for by the attachment. modifications required are modified to adapt it for the new uses pro- The only milling out portions of the arm 10 as indicatedk by the dotted lines in Fig. 1, at 22 and 23.

' The milled out portion 22 facilitates readings on the scale and increases the accuracy of the device and the milled out portion 23 provides a beveled shoulder 24.

With the device litted with the improved attachment and modified as described, it can be used as a depth gage.

Also it can be used as an inside caliper by adjusting it so that the outer edges of the shouldered portions 21 and 24k contact with the opposite inside surfaces` ofthe article to be measured, in this event the width of the two shoulders being added to the reading.

lVhen used as an outthe stud 11.

1 -L' v. Fiom the ioiegoing description it will be seen that the improved attachment for depth gages increases the uses of a depth gage and converts the same into a handy, combination tool.

The modifications required are very simple and are easily made by the ordinary mechanic.

ZAlso the attachment is of very ing,` a straight beveled edge and an opposite tapering edge, the tapering edge portion of said arm being` out away and beveled to form :i measuring shoulder, one end portion of the arm being' of biiureated 'form to receive said l5 Seele et right angles tothe Straight edge of the erm and screw ineens for Clamping the erin to the Sonie. f Y

In testimony whereof, I affix my signature.
